人们对硒在某些退行性疾病（如癌症和心血管疾病）中的预防作用越来越感兴趣，这促进了对硒的天然来源的研究。本研究对120多种日本食品中的总硒含量进行了测定。通过测定亚硒酸盐与2,3 -二氨基萘反应产生的吡硒醇的荧光来测定硒的浓度。作为日本人的主食，大米中的硒含量低于其他国家。但肉类和鱼类产品中硒的平均含量是其他国家中最高的。虽然所选食品的样本数量很少，但结果描述了日本食品中硒含量的情况。
The growing interest in the prevention role of selenium in certain degenerative diseases such as cancer and cardiovascular disease has fostered research on natural sources of selenium. In this research, total selenium concentrations in over 120 items of selected Japanese foods were determined. The selenium concentration was measured fluorometrically by measurement of the fluorescence of piazselenol resulting from the reaction of selenite with 2, 3-diaminonaphtalene. The selenium level in rice, which is the staple food consumed in Japan, is lower than the other countries. But the mean levels of selenium in meat and fish products are among the highest values reported in other countries. Although the numbers of samples of selected foods analyzed are small, the results describe the picture of the selenium level of Japanese foods.
